Format to Currency problem

OS info

Problem description

There is no Wappler method to create this code:

Total Amount: {{dsCart.data.sum(`productprice * quantity`).formatCurrency("$", ".", ",", "2")}}

Steps to reproduce

Using the excellent Creating a Shopping Cart with the Data Store Component tutorial, I finish up with

Total Amount: {{dsCart.data.sum(`productprice * quantity`)}}

I want this to be formatted as currency.

In Data Formats, there is no Format to Currency option:

So I add To Number, after which I can select To Currency:

Selecting this gives me the this warning:

Removing the To Number step, gives me a similar warning.

Workaround

Hand code.

Total Amount: {{dsCart.data.sum(`productprice * quantity`).formatCurrency("$", ".", ",", "2")}}
